What is sin?
Sin is the beginning and result of human desire.
Uncontrollable desire turns into sin.
The Buddha said that everything has a cause and effect.
The moment when desire just sprouts, it seems insignificant, but maybe it is the turning gear of fate.
What kind of sin and what kind of sin, everything depends on the human heart.
"Why do you think the deceased did this?"
"Maybe this is obsession, just like I do to you!"
